View Full Version : Parent constructor not invoked with Python

I have the code
class A:
def __init__(self):
print('Class A loaded')
class B(A):
def __init__(self):
print('Class B loaded')
b = B()
and this produces the output,
Class B loaded
I have more of C and Java background and in them the parent constructor is automatically invoked when the parent class is created, but why not in python. Why is the parent constructor not invoked ???

c++ actually
Then be more careful typing here. Bachstelze gets grumpy when people mix C and C++. ;)
